' of the platform 4.

.front and rear ends is a section on line a a Fig. 1. Fig. 5 is a plan view of the hitch.

The frame of the harrow comprises. the two end bars 1 and 2 connected by the side bars 3. A platform 4 is. secured to the end and side bars of the frame. To each of the end bars 1 and 2 is secured a bar 5 having curved ends '6 projecting beyond the edges Transverse and centrally of the platform 4 are secured two bars 7 having their ends projecting beyond the platform. To the ends of the bars '7 projecting beyond the front edges of the platform are pivotally connected two disk gangs .8 and to the ends of these bars projecting beyond the rear edges of the platform are pivotally connected two disk gangs 9.

Guides 10 are slidably mounted on the respectively of the curved sections 6 of the bars 5, and the outer ends of the disk gangs 8 and 9 are pivotally connected to these guides.

Two hand levers 12 one for each of the rear disk gangs, are pivoted to the bars 5 on the bolt 13. A rod 14 connects veach lever below its fulcrum with the slidable guide 10 for the corresponding rear gang. A toothed segment 15 is provided for each of the levers forward ends of the bars 7 by the links 21.

A draft link 22 is connected to the draft bar 19 by the 23.

ent 16, and a hand lever 17 is pivoted guides, and

The barrow is drawn over the ground by being connected with a tractor and by meansv of the hand levers 12 all four disk gangs can be adjusted parallel with the sides of the gatform or angularly with respect thereto.

y means of the hand lever 17, the forward disk gangs can be adjusted independent of the rear disk gangs.

I claim as my invention.

1. A disk harrow comprising a platform, four disk gangs, edge and two at the rear edge of the platform having their inner ends pivotally con nected to the platform, curved guide-ways extending from the platform, a guide supported by each guide-way, and a pivotal connection between a way.

2. In apparatus of the character set forth, the combination with a frame, of front and rear sets of disk gangs pivoted at their inner ends to the central portion of the frame, and

' means mounted on the outer portions ofthe frame and connected to the corresponding front and rear gangs for simultaneously swinging the latter.

3. In apparatus of the character set forth, the combination with a platform, of a front set of gangs pivoted at their inner ends to the central portion of the platform and arranged in advance of the same, a rear set of gangs pivoted at their inner ends to the central portion of the platform and arranged in rear of the same, and means mounted on the outer portions ofthe platform and connected to the gangs for swinging the corresponding front and rear gangs.
